Absolutely requires very fast current and high oxygen levels at low aquarium temperatures 18-24°C (64.4-75.2°F) . This isn't considered a fragile fish because so many ignore these requirements. It is highly recommended that one read and apply Martin Thoene's profile and river tank article before considering this fish (See link below). Has very slow growth rate in captivity.

A flat bellied fish with very low profile, the Hillstream loach's body type is clearly built for fast water. Its yellow-brown body appears covered in black polka dots. Dorsal and anal fins are transparent with opaque stripes.
